High-Current SmartDrive DC Motor Driver for Precision Bi-Directional Motor Control
The MDS40B 40A SmartDrive DC Motor Driver is engineered for demanding motion control applications requiring reliable, high-current operation and flexible input control. Designed to drive a single brushed DC motor, it supports a wide motor voltage range from 10V to 45V and delivers up to 80A peak current, intelligently derating to 40A based on temperature for safe, continuous use. With a 16kHz switching frequency, the driver ensures quiet operation, making it suitable for robotics, automation, electric vehicles, and high-power actuator systems. Advanced protection features such as regenerative braking, thermal protection, temperature-based current limiting, and LiPo battery low-voltage warning enhance system reliability, while multiple input modes allow seamless integration with RC systems, microcontrollers, and industrial controllers.
